I'd like to enable link time optimization.
Unfortunately, the dependency proc_macro_hack_impl
fails to build when I enable LTO via RUSTFLAGS
.
I can run cargo build
with -v
and re-run the last rustc
build/link via manual copy/paste and added -C lto=thin
. This results in a significant performance improvement in the resulting binary.
But, is there a way to do this cleanly without re-running rustc
manually?
